PTC THERMISTOR

摘要

A PTC thermistor in which inner- and outer-layer electrodes composed of metallic foil are respectively stuck to conductive sheets with high adhesive strengths and has a larger current breaking characteristic. The thermistor contains a laminated body (13) which is formed by alternately laminating a plurality of conductive sheets (14) and an inner-layer electrode (11) composed of metallic foil having first plated layers (12) on both surfaces upon another so that the conductive sheets (14) can become the outermost layers of the laminated body (13) and, on the surfaces of the conductive sheets (14) constituting the outermost layers of the laminated body (13) facing the electrodes (11), the outer layer electrodes (18) having second plated layers (16) are provided. In addition, side-face electrode layers 20 are provided on the opposed side faces of the laminated body (13) so that the layers (20) can be connected electrically to the electrodes (11 and 18).
